You are given a qubit which is guaranteed to be either in or in state.
Your task is to perform necessary operations and measurements to figure out which state it was and to return 1 if it was a state or -1 if it was state. The state of the qubit after the operations does not matter.
You have to implement an operation which takes a qubit as an input and returns an integer.
Your code should have the following signature:
namespace Solution { open Microsoft.Quantum.Primitive; open Microsoft.Quantum.Canon; operation Solve (q : Qubit) : Int { body { // your code here } }}
